I bought Canon MP 258 with continuous ink supply system from low yat. The personnel already lock the ink supply and reminded me to release it before printing. However, I forgot to do just that and started printing directly after installing it. After a few pages, the alarm lights started blinking in orange colour and error code 5100 prompts out ( at the LED screen on the printer it displays alternately P and 2 ). Then I realised, I have not released the lock. Now, I can't make the ink to flow into the modified cartridge. Any suggestions or workaround?Thank you.
